• Local OS Version: win10 - 22h2 / 19045.51.31
• Remote OS Version: Fedora/40
• Remote Extension/Connection Type: WSL

• Logs:
  [9409 ms] Start: Run in container: # Test for /root/.ssh/known_hosts and ssh

  [9473 ms] Start: Run in container: cat /workspaces/redacted/.devcontainer.json 2>/dev/null
  [9478 ms] Repository redacted/redacted has no dev container files.

Steps to Reproduce:
set
"dev.containers.executeInWSL": true
have multiple devcontainer configurations (https://containers.dev/implementors/spec/#devcontainerjson)
/workspaces/redacted/.devcontainer/a/devcontainer.json
/workspaces/redacted/.devcontainer/b/devcontainer.json

extension blocks with popup to add devcontainer claiming no projects exists.

Problem does not occur when executing outside WSL.

The current workaround is to use a default config (.devcontainer/devcontainer.json, maybe adding it the first time) and then use F1 > Dev Containers: Switch Container to change to the desired configuration.
